To (1 Z-UhOT/b it may concern:

Be it known that 1, WILLIAM THOMAS HEsKETn, a subject of Great Britain,residing at Stones House, Hayfield, in the county of Derby, England,have invented new and useful Improvements in Machines for PrintingCloth, VValLPaper, and other Materials, of which the following is aspecification.

My invention relates to improvements in machines for printing cloth,wall paper and other materials and has for its object to enable aprinter to observe and distinguish objects printed on cloth, wall paperand other materials while traveling through the printingmachine.

Hitherto, in calico printing, a speed of about sixty yards a minute isconsidered the limit because of the diiliculty, even'at that speed, ofviewing and distinguishing the objeets printed and detecting any faultsof printing, such as imperfections ofregi'ster. llf, however the printercould observe the objects printed in such a way that he would be able todistinguish and detect any imperfections of register or faults ofprinting, a vastly increased speed and rate of printing couldreadily beattained and the object of my invention is to enable the printer to soobserve and distinguish the objects printed. l accomplish this object bythe arrangement use and application of a device such as a rotating diskhaving observation slits or apertures placed in front of the printingmachine at a suitable height and close to the cloth or other material asit leaves the engraved roller or other printing surface.

The disk is mounted on a carriage fitted on a traverse screw orotherwise suitably mounted so as to be capable of being moved to and froacross the face of the cloth or other material and stopped at anydesired point in it's traverse. The disk isrotatedby worm or othersuitable gearing actuated preferably from the driving shaft of theprinting machine so that the rotations of the disk synchronize with thespeed of travel of the material being printed.

In the accompanying sheet of drawings Figure 1 is av perspective view ofa calico which'my invention has been applied. Fig. 2 is a front view ofthe stationary. masking disk. Fig. 8 is a similar view of the rotatingdisk and. Fig. 4 is a side view of both disks and the worm gearing fordriving the rotating disk. I

On the frame a of the machine I mount in bearings Z) a screw 0 which isdriven in either direction as required by open and cross belts, notshown, and the well known arrangement of two fast pulleys d, (1 and 'aloose pulley (P. ()n the screw 0 is mounted a carriage e which istraversed to the desired position to or fro along the face of the clothf being printed whenever one of the driving belts is on one of the fastpulleys d, (P. A short shaft 9 is journaled in the carriage e and onthis shaft is fixed the rotating disk It in which are formed anysuitable number, say four, observation apertures h.

To prevent the eye becoming confused I prefer to mount on the travelingcarriagee in front of the rotating disk h a masking disk 'L with only asingle aperture i which can l :e fitted with a magnirying lens to assistthe vision of the observer. This disk i is held against movement by thefrictional engagement of its carrying parts but it may be rotated byhand when desired as it is su'lliciently loose to permit such movement.

An electric or other light may be -laced above the traveling carriage ewith a re ector, if required, to focus the light on to the part of theprinted material to be observed. On the shaft 9 of the rotating disk Itis also fiXeda worm wheel j which gears with a worm is mountedinbearings Z on the machine frame a and this worm 7c is driven by bevelgears m from a bevel gear a fixed on a shaft 0 carried in brackets psecured to the frame a. The shaft 0 is driven b a sliding friction wheel(1' mounted thereon 'rom a friction disk 1" fixed on the main shaft orother convenient rotat ing art.

o vary the speed of the shaft 0, and consequently the speed at which thedisk h is rotated, the friction wheel q is fitted to slide on a featherkey in the shaft 0 and it is moved nearer to or farther from the centerof the friction disk 1" by means of a guide bar 3 the boss of which ismounted on a screw 6 journaled at its ends in the brackets p and actuatuated by a hand wheel. a. The lower end of the har s is guided by a rod4) also supported in the brackets p.

in application the disk can be used in at least three ways for exam le:

First. The disk 1, can be rotated so that a Secondly.

sage of the observation apertures h exactly single Fobservation a ertureh therein will pass the eye of the 0 server say about three nmdred timesa minute, or to avoid rapid' rotation of the disk ii there may be two,three or more observation slits or a ertures 72- therein, equidistantfrom each ot ier, and in such case the rate of rotation of the disk may'be reduced. As the objects which are p'rin t-. ed on the cloth arealways exactly equidis tant from each other, repeating at a specifieddistance. it follows that if the printed objects pass at a rate that isa multiple of three hun.-; dred times per minute, the objects willappear to be stationary, although in fact, only a certain number areseen of those that pass.

If, after having made the passynchronize with the assage of the printedobjects as-above described, the driving is adjusted by operating thehand wheel 11, so as to cause the disk 'h to rotate rather slower, the

effect will be that the printed objects will appear to be gaining, thatis, moving forward rather quicker than the disk. 1

*Thirdly. If, after synchronizing, the motion of the rotation of thedisk 71 is slightly accelerated by again actuating the hand wheel u, theeffect will be that the printed objects ap ear to be losing, that is,moving slowly bac By utilizing the second and third modes the printer isable to examine the surface of, the-cloth or other material between theprinted objects in order to detect printing faults.

What I claim and desire to secure by Letters Patent of the United Statesis In a machine for-printing cloth, wall paperor other materials 1..The'combination with .a printing maacross the face of the material.being rinted,

a rotating disk mounted on the trave ing carriage and having anysuitable number of observation apertures, a stationary masking disk witha single aperture mounted on the carriage in front of the rotating diskand means for varying the speed of the rotating disk, all substantiallyas and for the purposes herein set forth.

3. In combination, the traveling carriage e,

the traverse screw 0 and means for rotating the same in eitherdirection, the rotating disk h having any suitable number ofobservation' apertures h and thenormally stationary masking disk i witha single aperture 6" said disk i being capable of rotary movement andmeans for rotating the disk'h and varying its speed, all substantiallyas and for the purposes herein described.

In testimony whereof I have signed my name to this specification in thetwo subscribing witnesses. WILLIAM THOMAS HESKETH.
